The sentence came hours after jurors heard relatives of Martinez Hernandez testify that she was a kind mother to her 3-year-old son who was never known to be violent. And defense attorneys talked about the tragedy of the situation and asked jurors to grant their client probation.

Martinez Hernandez was convicted of running over 24-year-old Yunuel Aguilar on May 19, 2013 after an argument. Martinez had told police after her arrest that she did not realize she hit her cousin that night and did not intend to harm her.

“There are not going to be any winners here today,” defense attorney James Jamison said during closing arguments. “Her life, along with the family and loved ones, is going to be changed forever.”

But Aguilar’s husband, Salvador Guzman testified Thursday that his children ask him every day what they will do without their mother.

Guzman, who was the father of Aguilar’s unborn child, has two other children with Aguilar and also provides for her oldest child.

Dallas County prosecutors and other witnesses said Martinez Hernandez had a tendency to snap when angry. Prosecutor Justin McCants said her actions the night she ran over the pregnant Aguilar were cold-hearted.

“The difference between you and the defendant,” McCants told jurors, “is that you wouldn't have snapped the way she did. You would have gotten out to help your cousin who you supposedly love. You wouldn't have lied to the police.”

“I’m going to ask you to send her to prison for 20 years,” he said. “You have two dead people and a family that won’t get to see either of them again.”
